Patented April 20, 1909.

Application filed April 11, 1908. Serial No. .426 ,582.

To all whom it may concern:

Be it known that 1, GEORGE H. HoUoK, a citizen of the United States,residing at Tonawanda, in the county of Erie and State of New York, haveinvented a new and useful quickly raised or lowered as desired bytherider, and securely retained in any adjusted position. V

A further object of the invention is to provide a support having meanswhereby the handle-bar may be readily detached from or attached to thestem of a bicycle head.

In the drawings :Figure 1 is a perspective view of the support, showingthe same applied to the head of a bicycle. Fig. 2 is a verticalsectional view of the invention, with the parts removed from the head.Fig. 3 is r a detail vertical sectional viewtaken'on the line 3-3 ofFig. 2. Fig. 4 is a perspective view of one of the handle clampingmembers. Fig. 5 is a perspective view of the other clamping member.

Similar reference numerals designate corresponding parts in all thefigures of the drawings.

Referring to the drawings, 1 designates the head of a bicycle which isprovided with a tubular stem 2 that is adapted to enter the steeringfork tube. The lower end of the stem is provided with a plurality oflongitudinal slots 3 of a sufficient length for the purpose hereinafterexplained. The upper end of the stem forms a rearwardly extendingresilient clamping member 4, which terminates in an ear 5 that is spacedfrom the body portion of the stem, and is provided with a smooth bore oropening 6 that is in alinement with the bore of the stem 2. The upperpart 7 of the body portion of the stem is of greater thickness in crosssection than the lower part, and is interiorly threaded as shown in Fig.2 by the numeral 8, the bottom of said threaded portion forming ashoulder 9. A hollow clamping bolt 10, having a head 1 1 and a shank 12,that is provided with threaded portions 13 and 14 respectively, whichare spaced apart by a smooth portion I the stem 2. The upper end of saidbolt passes through and beyond the bore 6 of the ear 5, and is providedwith a nut 16, which is adapted to bear against the top surface of theear 5 and thereby force the said ear downwardly toward the body portionof the stem. A bolt 17, having a squared head 18 I and a threaded shank19 passes through the hollow bolt 10, and the stem 2, and terminates ashort distance below the bottom of said stem. The bolt 17 is screwedinto a hollow tapered nut 20 that is adapted to be brought inside andbear against the wall of the stem and thereby expand the same.

The features thus far described constitute no 'part of my invention,except as they enter into and form elements of the combination of partsto which I lay claim.

The handle bar is retained in its desired position by means of anadjustable clamp constituting a support, which clamp comprises tworearwardly tapered arms 21 and 22, each having an integral and hollowinwardly extending gudgeon 21 and 22 respectively, as clearlyillustrated in Figs. 4 and 5 of the drawings. These gudgeons are adaptedto enter the opposite ends of the rearwardly extending clamping member 4and to be clamped therein by means of the nut 16. The opposite end ofthe arm 22 forms an inwardly extending flat bearing 23 having a threadedopening 24, and an upturned resilient clamping member 25 which isprovided at its extreme end with a sub stantially vertical ear 26 havinga threaded opening 27 therein. The corresponding end of the other arm 21forms an inwardly extending flat bearing 28 having an opening 29therein. This bearing is adapted to rest upon the bearing surface 23 ofthe other arm in such a manner that the two openings 29 and 24respectively register. These two arms are held in this relation by a setscrew 30 which passes through the opening 29 and into the threadedopening 24. The bearing 28 of the arm 21 terminates in an upturnedclamping member 31 of suflicient length to fit between the bearing 23and the ear 26, and is provided with a substantially vertical ear 32having a threaded opening 33 that is adapted to register with thecorresponding opening 27 of the ear 26. The handle bar 34 is positionedbetween the two clamping members 25 and 31, and is adapted to beretained at any angle by means of a screw 35 which is threaded into thetwo registering openings 27 and 33, thereby clamping the two memberssecurely to said handle bar.

From the foregoing description, it will be readily observed that byloosening the clamping member 4, the handle bar can be quickly arrangedat different elevations, and then secured at any position desired by therider. Furthermore, the handle bar can be quickly arranged at anysuitable angle as desired. It will be noted that the screw 35 of thehandle bar clamp, not only serves to secure the handle bar, but preventsany tendency of the two gudgeons from becoming unseated from theresilient clamping member 4.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. A handle bar support comprising a tubular stem, the top end thereofforming a rearwardly extending resilient loop, that is provided with anear having an opening in register with the stem, a hollow clamping boltscrewed into the upper part of the stem and extending through and abovethe ear of the loop and provided with a nut, a support comprising armsthat are provided with gudgeons adapted to enter the resilient loop andto be clamped thereto, means for securing the arms together, and a clampformed by the opposite ends of the arms and adapted to grip the handlebar and prevent any movement thereof.

2. In a handle bar support, the combination with a stem having aclamping member, of an extension support comprising two arms, a gudgeonprovided on one end of each arm, said gudgeons being secured to theclamping member, registering openings provided in the arms at anintermediate point, a fastening screw passed through the openings forholding the arms together, a seetional clamp formed by the opposite endsof the arms and adapted to embrace the handle bar, and a set screw forsecuring the sections of the clamp to the handle bar and also serving toprevent any outward movement of the arms.

3. In a handle bar support, the clamp consisting of two arms, eachhaving a gudgeon at one end, the intermediate portions of the armsoverlapping and provided with registering openings, a set screw passedthrough the openings, the other ends of the arms each carrying a sectionof aelamp tor the handle bar, and a screw for securing the sections ofthe clamp together.

4:. In a handle bar support, the combination of the bicycle head havingthe rearwardly extending resilient loop, means for expanding andcontracting said loop, a clamp constituting an extension support for thehandle bar and consisting of two arms, the front ends of which eachlmving a gudgeon to lit in said loop, and a sectional clamp provided atthe other ends of said arms to embrace and grip the handlebar, each armcarrying a section of the clamp.

In testimony that I claim the foregoing as my own, I have hereto allixedmy signature in the presence of two witnesses.

GEORGE ll. HONOR.
